Suppose f(x) = 2x + 5 and g(x) = -1/3x + 2. Find f(1)/g(3)

stira [4]

<span>Given- f(x) = 2x + 5 g(x) = (-1/3)x + 2 , f(1)/g(3) = ? Solution- f(1) = 2*1 + 5 f(1) = 7 g(3) = (-1/3)*3 + 2 g(3) = -1 + 2 g(3) = 1 So, f(1)/g(3) = 7/1 f(1)/g(3) = 7</span>

What is the simplified version of 10/20?

Amanda [17]

We can divide the numerator and denominator by 10.

10 / 10 = 1
20 / 10 = 2

So the simplified version is 1/2.

OBC is a sector of a circle with centre o and radius 9cm work out the area of the shaded region as a percentage of the area of s

NARA [144]

Answer:

83.7 %

Step-by-step explanation:

To get the area of the shaded region, we will following these steps.

Step one: Get the area of the sector of the circle.

The area of the sector of the circle can be obtained using the formula:

$Area = \frac{\theta}{360}\times \pi r^{2}$

Theta will be 60 degrees because triangle OAD is an equilateral triangle

Hence, $Area = \frac{60}{360}\times \pi \times 9^{2}= 42.42cm^{2}$

Step Two: Get the area of the equilateral triangle

The area of the equilateral triangle can be got using the formula

$Area = \frac{1}{2} Base \times Height$

The height of the triangle can be got by drawing an imaginary line bisecting the triangle into two parts and applying the Pythagoras' theorem to any of the resulting right-angled triangles formed.

This will be $height =\sqrt{4^{2}-2^{2}} =3.46cm$

Thus $Area = \frac{1}{2}\times 4\times 3.46=6.93cm^{2}$

Step Three: Subtract the area of the triangle from the area of the sector

Area of the shaded portion = $42.42cm^{2}-6.93cm^{2}=35.49cm^{2}$

Step Four: Divide the area of the shaded portion by the area of the entire shape and multiply the result by 100:

Expressing the ratio of the two areas as a percentage, we have

$\frac{35.49}{42.42} \times 100\approx 83.7 %$ %
